If Expressions

Zig's if statements accept bool values (i.e. true or false). Unlike languages like C or JavaScript, there are no values that implicitly coerce to bool values.

Ternary conditional operators (cond ? a : b) do not exist in zig.

const expect = @import("std").testing.expect;

test "if statement" {
    const a = true;
    var x: u16 = 0;
    if (a) {
        x += 1;
    } else {
        x += 2;
    }
    try expect(x == 1);
}

If statements also work as expressions.

const expect = @import("std").testing.expect;

test "if statement expression" {
    const a = true;
    var x: u16 = 0;
    x += if (a) 1 else 2;
    try expect(x == 1);
}
